Description

La présente invention se rapporte au domaine des systèmes de détection optique utilisés pour l'aide à la conduite des véhicules automobiles, et elle concerne plus particulièrement les dispositifs de nettoyage des capteurs de ces systèmes.The present invention relates to the field of optical detection systems used to aid the driving of motor vehicles, and it relates more particularly to the devices for cleaning the sensors of these systems.

Un dispositif de nettoyage de capteurs d'un système de détection optique est connu du document EP2949520 .A device for cleaning sensors of an optical detection system is known from the document EP2949520 .

Des systèmes de détection optique équipent un nombre de plus en plus grand de véhicules automobiles afin d'aider le conducteur du véhicule dans certaines situations de conduite, comme par exemple, l'aide au stationnement au moyen d'une caméra de prise de vues ou d'un radar de type infrarouge. Pour que ces dispositifs d'aide à la conduite soient le plus efficace possible, il est indispensable que les capteurs optiques de ces systèmes de détection soient propres, qu'il s'agisse de la lentille d'une caméra ou d'un autre type de capteur optique, et par exemple des capteurs laser (communément appelés LIDAR) ou autres capteurs basés sur l'émission et/ou la détection de la lumière dans le spectre visible ou invisible pour l'Homme, en particulier l'infrarouge.Optical detection systems are equipping an increasing number of motor vehicles in order to help the driver of the vehicle in certain driving situations, such as, for example, parking assistance by means of a camera or an infrared type radar. For these driving assistance devices to be as effective as possible, it is essential that the optical sensors of these detection systems are clean, whether it is the lens of a camera or another type. optical sensor, and for example laser sensors (commonly called LIDAR) or other sensors based on the emission and / or detection of light in the spectrum visible or invisible to humans, in particular infrared.

Il est connu de placer, au voisinage de ces capteurs optiques, un dispositif de nettoyage apte à projeter une quantité déterminée de liquide de nettoyage sur le capteur optique associé juste avant que soit réalisée la prise de vue ou la détection. Et, afin d'éviter tout risque de pollution du capteur considéré par d'éventuelles traces qu'un tel liquide de nettoyage pourrait laisser (gouttes, coulures, etc ...), il est également connu de procéder à la projection, après celle du fluide de nettoyage, d'un fluide de séchage, notamment de l'air, qui permet de débarrasser le capteur optique du liquide de nettoyage et des salissures résiduelles que celui-ci entraîne alors avec lui. On comprend que ces dispositifs de nettoyage ne doivent toutefois pas gêner le fonctionnement du capteur en trouvant dans le champ de vision du capteur lorsque celui-ci est en fonctionnement.It is known practice to place, in the vicinity of these optical sensors, a cleaning device capable of projecting a determined quantity of cleaning liquid onto the associated optical sensor just before the picture is taken or the detection is carried out. And, in order to avoid any risk of pollution of the sensor considered by possible traces that such a cleaning liquid could leave (drops, runs, etc.), it is also known to proceed with the projection, after that. cleaning fluid, a drying fluid, in particular air, which makes it possible to rid the optical sensor of the cleaning liquid and of the residual dirt which the latter then carries with it. It will be understood that these cleaning devices must not however interfere with the operation of the sensor by being in the field of view of the sensor when the latter is in operation.

Pour cela, les éléments permettant la distribution des fluides de nettoyage et/ou de séchage sont généralement aptes à être déplacés entre une position de travail dans laquelle ils viennent se placer sensiblement en avant du capteur optique pour en assurer le nettoyage, et une position de repos dans laquelle ils sont rétractés par rapport au capteur pour ne pas gêner son fonctionnement. Par ailleurs, ces dispositifs doivent être le plus compact possible pour répondre aux contraintes d'encombrement au sein de l'espace restreint du véhicule dans lequel est accueilli le dispositif d'aide à la conduite.For this, the elements allowing the distribution of cleaning and / or drying fluids are generally able to be moved between a working position in which they are placed substantially in front of the optical sensor to ensure cleaning, and a position of rest in which they are retracted relative to the sensor so as not to interfere with its operation. Furthermore, these devices must be as compact as possible to meet the size constraints within the restricted space of the vehicle in which the driving assistance device is accommodated.

La présente invention a pour but de proposer une solution qui permette de faciliter l'implantation d'un tel ensemble de détection optique et du dispositif associé de nettoyage de son capteur optique, et qui permette un pilotage simple de ce dispositif de nettoyage entre les positions de travail et de repos.The object of the present invention is to propose a solution which makes it possible to facilitate the installation of such an optical detection assembly and of the associated device for cleaning its optical sensor, and which allows simple control of this cleaning device between the positions. of work and rest.

Dans ce but, l'invention propose un dispositif de nettoyage d'un capteur optique d'un système de détection optique pour véhicule automobile, qui comprend un ensemble d'acheminement et de distribution d'un fluide de nettoyage et d'un fluide de séchage. Selon l'invention, le dispositif de nettoyage comporte des moyens motorisés électriques pour déplacer selon un mouvement linéaire cet ensemble d'acheminement et de distribution de fluides entre une position de travail, dans laquelle les fluides peuvent être distribués sur une surface extérieure du capteur optique et une position de repos.To this end, the invention provides a device for cleaning an optical sensor of an optical detection system for a motor vehicle, which comprises an assembly for conveying and distributing a cleaning fluid and a cleaning fluid. drying. According to the invention, the cleaning device comprises electric motorized means for moving in a linear movement this assembly for conveying and distributing fluids between a working position, in which the fluids can be distributed on an exterior surface of the optical sensor. and a resting position.

Les moyens motorisés électriques présentent en sortie un arbre d'entraînement rendu solidaire de l'ensemble d'acheminent et de distribution de fluides, ledit arbre d'entraînement étant déplacé linéairement et donc susceptible de transmettre à l'ensemble d'acheminement et de distribution ce mouvement de translation généré par les moyens motorisés électriques. Selon différents modes de réalisation, on pourra prévoir que les moyens motorisés électriques consistent soit en un actionneur linéaire, ledit arbre d'entraînement consistant alors en une tige de sortie de l'actionneur directement translaté, soit en un moteur rotatif, ledit arbre d'entraînement consistant alors en une crémaillère actionnée par un pignon solidaire d'un rotor dudit moteur.The electric motorized means have at the output a drive shaft made integral with the assembly for conveying and distributing fluids, said drive shaft being moved linearly and therefore capable of transmitting to the assembly for conveying and distributing this translational movement generated by the electric motorized means. According to different embodiments, provision may be made for the electric motorized means to consist either of a linear actuator, said drive shaft then consisting of an output rod of the directly translated actuator, or of a rotary motor, said shaft of drive then consisting of a rack actuated by a pinion integral with a rotor of said motor.

On pourra prévoir une série de caractéristiques, prises seules ou en combinaison, propres à la configuration d'un dispositif de nettoyage dans lequel l'ensemble d'acheminement et de distribution de fluides, qui comprend au moins un embout de raccordement pour l'alimentation de chacun des fluides et des conduites de distribution vers une ou plusieurs buses de projection de ces fluides, est accueilli dans un boîtier configuré pour coopérer avec l'arbre d'entraînement.It is possible to provide a series of characteristics, taken alone or in combination, specific to the configuration of a cleaning device in which the assembly for routing and distributing fluids, which comprises at least one connection end for the supply. of each of the fluids and distribution pipes to one or more spray nozzles for these fluids, is accommodated in a housing configured to cooperate with the drive shaft.

Ce boîtier pourra notamment comporter une zone de fixation de l'arbre d'entraînement, une partie de distribution, porteuse d'au moins une buse de projection de fluide, et une partie d'alimentation, porteuse d'au moins un embout de raccordement et d'au moins une conduite de distribution.This housing may in particular include a drive shaft fixing zone, a distribution part, carrying at least one fluid projection nozzle, and a supply part, carrying at least one connection end piece. and at least one distribution line.

La zone de fixation pourra former une extension du boîtier décalée par rapport au passage de la au moins une conduite de distribution, et notamment décalée du même côté du boîtier que le côté sur lequel est agencée la au moins une buse de projection de fluide.The fixing zone may form an extension of the housing offset with respect to the passage of the at least one distribution pipe, and in particular offset on the same side of the housing as the side on which the at least one fluid projection nozzle is arranged.

Selon des caractéristiques de l'invention relatives à cette zone de fixation, celle-ci peut présenter une encoche de formes et de dimensions correspondantes à celles de la section de l'arbre d'entrainement. L'encoche peut être borgne, et elle peut être de forme rectangulaire correspondante à une forme rectangulaire de la section de l'arbre d'entrainement.According to characteristics of the invention relating to this fixing zone, the latter may have a notch of shapes and dimensions corresponding to those of the section of the drive shaft. The notch may be blind, and it may be of a rectangular shape corresponding to a rectangular shape of the section of the drive shaft.

Selon différents modes de réalisation de l'invention, ce moteur électrique peut être un moteur à sortie linéaire, ou un moteur à sortie rotative dans laquelle l'arbre de sortie est lié à une crémaillère, transformant ainsi le mouvement de rotation de l'arbre de sortie du moteur en un mouvement linéaire.According to different embodiments of the invention, this electric motor can be a linear output motor, or a rotary output motor in which the output shaft is linked to a rack, thus transforming the rotational movement of the shaft. motor output in a linear motion.

On comprend que le mouvement linéaire qui permet d'amener l'ensemble d'acheminement et de distribution en position de travail, pour que les buses de projection des fluides de nettoyage et/ou de séchage soient en regard du capteur optique à nettoyer, peut être dirigé selon différentes directions au regard du véhicule, sans que cela modifie le fonctionnement du dispositif de nettoyage selon l'invention.It is understood that the linear movement which makes it possible to bring the conveyor and distribution assembly into the working position, so that the spraying nozzles of the cleaning and / or drying fluids are opposite the optical sensor to be cleaned, can be directed in different directions with respect to the vehicle, without this modifying the operation of the cleaning device according to the invention.

Les moyens motorisés électrique peuvent comprendre un moteur pas à pas, qui est commandé pour générer un déplacement uniquement sur la distance entre la position de travail et la position de repos, ou bien ils peuvent comprendre un moteur continu, des butées de fin de déplacement étant prévues pour correspondre aux positions de travail et de repos de l'ensemble d'acheminent et de distribution de fluides.The electric motorized means can comprise a stepping motor, which is controlled to generate a movement only over the distance between the working position and the rest position, or they can comprise a continuous motor, end of movement stops being designed to correspond to the working and resting positions of the assembly for conveying and distributing fluids.

L'invention concerne également un système de détection optique pour véhicule automobile, comprenant au moins un capteur optique, et un dispositif de nettoyage de ce capteur tel qu'il vient d'être présenté.The invention also relates to an optical detection system for a motor vehicle, comprising at least one optical sensor, and a device for cleaning this sensor as has just been presented.

Other characteristics, details and advantages of the invention will emerge more clearly on reading the description given below by way of indication, in relation to the appended figures, in which:

Il faut tout d'abord noter que si les figures exposent l'invention de manière détaillée pour sa mise en oeuvre, elles peuvent bien entendu servir à mieux définir l'invention le cas échéant.It should first of all be noted that if the figures set out the invention in detail for its implementation, they can of course be used to better define the invention if necessary.

Par ailleurs, l'invention sera décrite dans ce qui suit dans son application à un système de détection optique comprenant une caméra de prise de vues équipée d'une lentille. Ainsi qu'il a été indiqué précédemment, l'invention ne se limite toutefois pas à cette application, et s'étend à tout système de détection optique du véhicule mettant en oeuvre au moins un capteur optique tel que, à titre d'exemples non exhaustifs : capteurs laser, capteurs basés sur l'émission et/ou la détection de rayonnement dans le spectre visible ou invisible.Furthermore, the invention will be described in what follows in its application to an optical detection system comprising a picture taking camera equipped with a lens. As indicated previously, the invention is not however limited to this application, and extends to any optical detection system of the vehicle implementing at least one optical sensor such as, by way of examples not comprehensive: laser sensors, sensors based on the emission and / or detection of radiation in the visible or invisible spectrum.

Les figures 1 et 2 illustrent schématiquement un système de détection optique associé à un dispositif de nettoyage réalisé selon un premier mode de réalisation de l'invention, le système de détection optique comportant ici une caméra 1 équipée d'une lentille 2.The figures 1 and 2 schematically illustrate an optical detection system associated with a cleaning device produced according to a first embodiment of the invention, the optical detection system comprising here a camera 1 equipped with a lens 2.

A ce système de détection optique est associé un dispositif de nettoyage de la lentille 2, formé notamment par un ensemble d'acheminement et de distribution d'un fluide de nettoyage et d'un fluide de séchage. Plus particulièrement, cet ensemble d'acheminement et de distribution présente des embouts de raccordement 3 et 4 à des tuyaux d'alimentation ici non représentés, respectivement pour l'acheminement d'un liquide de nettoyage depuis un réservoir de stockage non représenté, et pour l'acheminement d'un fluide de séchage, et il présente un ensemble de premières buses de projection 5, pour la projection du liquide de nettoyage, et un ensemble de deuxièmes buses de projection 6, pour la projection d'un fluide de séchage. Liquide de nettoyage et fluide de séchage circulent à l'intérieur d'un boîtier 7 de l'ensemble d'acheminement et de distribution, dans des conduites de distribution 8 venant alimenter les buses, les conduites étant représentées en traits pointillés sur la figure 4. Les buses de projection 5 et 6 sont aménagées au voisinage les unes des autres sur une même face du boîtier, à une première extrémité longitudinale de celui-ci, opposée à la deuxième extrémité longitudinale où s'étendent les embouts de raccordement 3 et 4.Associated with this optical detection system is a device for cleaning the lens 2, formed in particular by an assembly for conveying and distributing a cleaning fluid and a drying fluid. More particularly, this routing and distribution assembly has connection end pieces 3 and 4 to supply pipes not shown here, respectively for the routing of a cleaning liquid from a storage tank, not shown, and for the delivery of a drying fluid, and it has a set of first projection nozzles 5, for the projection of the cleaning liquid, and a set of second projection nozzles 6, for the projection of a drying fluid. Cleaning liquid and drying fluid circulate inside a housing 7 of the conveying and distribution assembly, in distribution pipes 8 which supply the nozzles, the pipes being shown in dotted lines on the diagram. figure 4 . The projection nozzles 5 and 6 are arranged in the vicinity of each other on the same face of the housing, at a first longitudinal end thereof, opposite to the second longitudinal end where the connection end pieces 3 and 4 extend.

Le boîtier 7 est rendu mobile pour se déplacer entre une position de travail, plus particulièrement illustrée sur la figure 1, dans laquelle les fluides projetés par les buses de projection 5 et 6 sont aptes à atteindre une surface extérieure de la lentille 2, et une position de repos, illustrée sur la figure 2, dans laquelle les buses de projection sont en retrait par rapport à la lentille 2 et dans laquelle le boîtier 7 peut avantageusement être escamoté dans un élément de carrosserie du véhicule. On comprend qu'aucun fluide n'est projeté en direction de la lentille lorsque le boîtier 7, et les buses de projection associés 5 et 6, sont dans leur position de repos, notamment lorsque cette position de repos est une position escamotée dans la carrosserie du véhicule.The housing 7 is made mobile to move between a working position, more particularly illustrated on the figure 1 , in which the fluids projected by the projection nozzles 5 and 6 are able to reach an outer surface of the lens 2, and a rest position, illustrated in the figure figure 2 , in which the projection nozzles are in retraction relative to the lens 2 and in which the housing 7 can advantageously be retracted into a bodywork element of the vehicle. It will be understood that no fluid is projected in the direction of the lens when the housing 7, and the associated projection nozzles 5 and 6, are in their rest position, in particular when this rest position is a retracted position in the bodywork. of the vehicle.

Selon l'invention, le mouvement du boîtier 7 et le mouvement de l'ensemble d'acheminement et de distribution constitué des embouts de raccordement 3 et 4, des buses de projection 5 et 6 et des conduites de distribution 8, est un mouvement linéaire obtenu par des moyens motorisés électriques 9. Tel qu'illustré sur les figures 1 et 2, le passage du boîtier 7 et de l'ensemble d'acheminement et de distribution associé, d'une position de travail à une position de repos, se fait par un mouvement de translation, en rapprochement ou en éloignement des moyens motorisés électriques. On limite ainsi la place nécessaire autour du dispositif de nettoyage pour qu'il puisse passer de sa position active à sa position de repos.According to the invention, the movement of the housing 7 and the movement of the conveying and distribution assembly consisting of the connection end pieces 3 and 4, the projection nozzles 5 and 6 and the distribution pipes 8, is a linear movement. obtained by electric motorized means 9. As illustrated on the figures 1 and 2 , the passage of the housing 7 and of the associated conveying and distribution assembly, from a working position to a rest position, is effected by a translational movement, towards or away from the electric motorized means. This limits the space required around the cleaning device so that it can pass from its active position to its rest position.

Les moyens motorisés électriques 9 sont pilotés par un dispositif de commande, qui envoie une instruction de mise en route des moyens motorisés électriques lorsqu'une information relative à l'utilisation du système de détection optique est reçue, que cette utilisation soit une utilisation à venir, ou une utilisation passée. En d'autres termes, une information d'imminence d'utilisation du système de détection optique, du type arrêt du véhicule et passage de la vitesse correspondant à la marche arrière, ou une information de fin d'utilisation du système de détection optique, peuvent déclencher une mise en oeuvre des moyens motorisés pour réaliser un nettoyage du capteur optique, avant ou après son utilisation. Sans instruction de mise en oeuvre, l'ensemble d'acheminement et de distribution des fluides de nettoyage et de séchage reste dans une position de repos, et les moyens motorisés électriques ne sont pas alimentés. Il en résulte un besoin énergétique limité pour cette fonction puisque les opérations de nettoyage sont épisodiques et rapides.The electric motorized means 9 are controlled by a control device, which sends an instruction to start the electric motorized means when information relating to the use of the optical detection system is received, whether this use is a future use. , or past use. In other words, information about the imminent use of the optical detection system, of the type stopping the vehicle and changing the gear corresponding to reverse gear, or information about the end of use of the optical detection system, can trigger the use of motorized means for cleaning the optical sensor, before or after its use. Without an operating instruction, the assembly for routing and distributing the cleaning and drying fluids remains in a rest position, and the electric motorized means are not powered. This results in a limited energy requirement for this function since cleaning operations are episodic and rapid.

On comprend que l'utilisation selon la présente invention de systèmes électriques permet de faciliter la détection du blocage du système, notamment en cas de gel. Le système de commande associé peut ainsi simultanément couper l'alimentation des systèmes mis en oeuvre, à savoir le moyen motorisé mais aussi la pompe par exemple, ce qui présente l'avantage de ne pas forcer sur les pièces du système.It will be understood that the use according to the present invention of electrical systems makes it possible to facilitate the detection of the blockage of the system, in particular in the event of freezing. The associated control system can thus simultaneously cut off the power supply to the systems used, namely the motorized means but also the pump for example, which has the advantage of not forcing the parts of the system.

Différentes variantes de réalisation peuvent être mises en oeuvre dans le cadre de l'utilisation selon l'invention de moyens motorisés électriques générant un mouvement linéaire de l'ensemble d'acheminement et de distribution associé.Different variant embodiments can be implemented in the context of the use according to the invention of electric motorized means generating a movement. linear of the associated routing and distribution set.

Des variantes peuvent notamment porter sur le type de moteur. On pourra indifféremment mettre en oeuvre un moteur électrique rotatif ou un moteur électrique linéaire, dès lors que l'arbre d'entraînement 10, en sortie des moyens motorisés électriques 9, connaît un mouvement linéaire qu'il sait transmettre au boîtier 7. Dans le cas d'un moteur électrique linéaire, le boîtier est directement monté sur l'arbre de sortie, tandis que dans le cas d'un moteur électrique rotatif, le boîtier est monté sur une crémaillère qui forme l'arbre d'entraînement, dont le mouvement est rendu linéaire par une liaison dentée avec une tige liée au rotor du moteur.Variants may in particular relate to the type of engine. It is equally possible to use a rotary electric motor or a linear electric motor, since the drive shaft 10, at the output of the electric motorized means 9, experiences a linear movement which it knows how to transmit to the housing 7. In the case of in the case of a linear electric motor, the housing is directly mounted on the output shaft, while in the case of a rotary electric motor, the housing is mounted on a rack that forms the drive shaft, whose Motion is made linear by a toothed connection with a rod linked to the motor rotor.

D'autres variantes peuvent porter sur le mode de fonctionnement du moteur et notamment son cadencement. Plus précisément, le mouvement linéaire peut être avantageusement obtenu par un moteur électrique du type pas à pas. Un tel moteur est dimensionné pour produire un déplacement déterminé de l'arbre d'entraînement en sortie du moteur, entre deux positions extrêmes, étant compris qu'une première position extrême de l'arbre d'entrainement correspond à la position de repos de l'ensemble d'acheminent et de distribution de fluides 3, 4, 5, 6, 7, 8, et qu'une deuxième position extrême de l'arbre d'entraînement correspond à la position de travail de cet ensemble. On pourra prévoir en variante de réalisation un moteur continu, associé des butées de fin de déplacement qui envoie une information de fin de course au module de commande du moteur électrique afin d'en stopper l'alimentation.Other variants may relate to the operating mode of the engine and in particular its timing. More precisely, the linear movement can advantageously be obtained by an electric motor of the stepping type. Such a motor is dimensioned to produce a determined displacement of the drive shaft at the output of the motor, between two extreme positions, it being understood that a first extreme position of the drive shaft corresponds to the rest position of the motor. 'assembly for conveying and distributing fluids 3, 4, 5, 6, 7, 8, and that a second extreme position of the drive shaft corresponds to the working position of this assembly. As an alternative embodiment, provision may be made for a continuous motor, associated with end-of-travel stops which sends end-of-travel information to the control module of the electric motor in order to stop the supply thereof.

Dans chacun de ces cas, le mouvement linéaire du boîtier 7 est généré par le déplacement linéaire de l'arbre d'entraînement 10, le long de la flèche F1 illustrée sur les figures 1 et 2.In each of these cases, the linear movement of the housing 7 is generated by the linear movement of the drive shaft 10, along the arrow F1 shown on the figures. figures 1 and 2 .

Selon une caractéristique avantageuse de l'invention, le boîtier 7 est directement fixé sur l'arbre d'entraînement 10 coulissant en sortie du moteur électrique 9. A cet effet, le boîtier 7 comporte une zone de fixation 12 portant une encoche 13 de formes et de dimensions correspondantes à celles de la section de l'arbre d'entrainement 10. Notamment, cette encoche 13 peut prendre une forme rectangulaire, dans laquelle est logé l'arbre d'entrainement de section rectangulaire également, ce qui permet d'interdire une rotation relative du boîtier par rapport à l'arbre d'entraînement autour de l'axe de coulissement de cet arbre.According to an advantageous characteristic of the invention, the housing 7 is directly fixed on the sliding drive shaft 10 at the output of the electric motor 9. For this purpose, the housing 7 comprises a fastening zone 12 carrying a notch 13 of shapes. and of dimensions corresponding to those of the section of the drive shaft 10. In particular, this notch 13 can take a rectangular shape, in which is housed the drive shaft of rectangular section also, which makes it possible to prohibit a relative rotation of the housing with respect to the drive shaft about the sliding axis of this shaft.

On pourra noter plus particulièrement que le boîtier comporte plusieurs parties distinctes parmi lesquelles une première partie de distribution 14, porteuse des buses de projection 5 et 6, une deuxième partie correspondant à la zone de fixation 12, et une troisième partie d'alimentation 15 porteuse des embouts de raccordement 3 et 4 et des conduites de distribution 8 représentées en traits pointillés sur la figure 4.It may be noted more particularly that the housing comprises several distinct parts, including a first distribution part 14, carrying the projection nozzles 5 and 6, a second part corresponding to the fixing zone 12, and a third supply part 15 carrying connection end pieces 3 and 4 and distribution pipes 8 shown in dotted lines on the figure 4 .

La zone de fixation 12 forme une extension décalée par rapport au passage des conduites de distribution de fluides, et ici notamment décalée du même côté du boîtier 7 que le côté sur lequel sont agencées les buses de projection de fluides, respectivement 5 et 6, sur ce boîtier. Ainsi, le flux de fluides dans les conduites de distribution 8, en provenance des embouts de raccordement 3 et 4, n'est pas perturbé par la présence de l'encoche 13 de la zone de fixation 12 et par la présence éventuelle de l'arbre d'entraînement 10 dans cette encoche. Il est, bien sûr, à noter qu'un tel mode de réalisation n'est pas exclusif : d'une manière générale, l'invention prévoit que la fixation du boîtier 7 avec l'arbre d'entraînement en sortie du moteur électrique 9 qui assure le mouvement linéaire de cet ensemble (qu'il s'agisse d'un arbre de sortie linéaire ou d'une crémaillère associée à un arbre de sortie rotatif) soit définie de telle manière qu'elle n'entraîne aucune perturbation du flux de ces fluides.The fixing zone 12 forms an extension offset with respect to the passage of the fluid distribution pipes, and here in particular offset on the same side of the housing 7 as the side on which the fluid projection nozzles, respectively 5 and 6, are arranged on this case. Thus, the flow of fluids in the distribution pipes 8, coming from the connection end pieces 3 and 4, is not disturbed by the presence of the notch 13 of the fixing zone 12 and by the possible presence of the drive shaft 10 in this notch. It should of course be noted that such an embodiment is not exclusive: in general, the invention provides that the fixing of the housing 7 with the drive shaft at the output of the electric motor 9 which ensures the linear movement of this assembly (whether it is a linear output shaft or a rack associated with a rotating output shaft) is defined in such a way that it does not cause any disturbance of the flow of these fluids.

L'arbre peut être emmanché ou fixé par vissage, dans cette encoche 13, ici représentée borgne. On pourrait prévoir une ouverture traversante en lieu et place d'une encoche, et prévoir là encore des moyens de fixation adéquates pour transmettre au boîtier 7 le mouvement linéaire de l'arbre d'entrainement.The shaft can be fitted or fixed by screwing, in this notch 13, here shown blind. It would be possible to provide a through opening instead of a notch, and again provide adequate fixing means to transmit to the housing 7 the linear movement of the drive shaft.

Telle qu'elle vient d'être décrite, l'invention permet, par des moyens simples, de réaliser un dispositif compact, et efficace dans le positionnement du dispositif de nettoyage d'un capteur optique d'un système de détection optique installé sur un véhicule automobile.As it has just been described, the invention makes it possible, by simple means, to produce a compact device, and efficient in the positioning of the cleaning device of an optical sensor of an optical detection system installed on a motor vehicle.

Ainsi qu'il a été mentionné précédemment, si l'invention a été ici décrite et illustrée dans son application à un ensemble optique mettant en œuvre une caméra de prise de vues, elle ne saurait se limiter à cette application, et elle s'étend à tout ensemble de détection mettant en oeuvre un capteur optique.As previously mentioned, if the invention has been described and illustrated here in its application to an optical assembly implementing a picture-taking camera, it cannot be limited to this application, and it extends to any detection assembly using an optical sensor.
